Based on my early studies, I think people's lives changed as a result of the Industrial Revolution in that society completely changed the way goods were produced or manufactured.
Indeed, the Industrial Revolution changed the way of many people. Farmers who lived in the rural parts of the country decided to move to the larger cities such as New York or Chicago, where the big factories were located. Immigrants from Europe and Asia decided to move to the United States to work in the factories. There, people were hired to operate the machines in the mass production system. They earn low salaries and worked under unhealthy and risky work conditions.
Answer:
Both breeches and pantaloons were worn during the 1810s. Breeches extended to the knee where they were fastened with buttons and a buckle or tie (Fig. 1); pantaloons, which had originated in the 1790s, were very tightly-fitted and longer, extending to the calf or ankle where they fastened with ties or buttons (Fig. 4)(Byrde 93; Johnston 14). Either could be worn during the day, but breeches were the proper evening attire with white stockings and evening pumps (Fig. 5). For daywear, both were frequently worn with tall boots, a favorite fashion of early nineteenth century menswear (le Bourhis 112). It was particularly in vogue to wear pantaloons tucked into “hessian” boots, defined by heart-shaped tops and tassels (Laver 160). Named for the Hessian mercenary soldiers from Germany, these boots and clinging pantaloons, which displayed a man’s leg muscles to great effect, lent a martial glamour to civilian dress (Ashelford 186; Johnston 14). The man in figure 1 of the Womenswear section sports pantaloons and hessians.
